Abstract

Abstract The barrier in a closure liner can be formed with a distinctive design or logo when the closure liner is inserted in the cap by placing a male embossing die against the sealing layer of the closure liner with sufficient force to emboss an image in the foil layer. The embossing of indicia into the liner at the time the cap is to be placed on the container provides the manufacturer with his own distinctive logo which cannot be readily duplicated thus making the container closure tamper-resistant.
